Natural Sound in Framingham, Ma. I had been a customer since the late 70's, having bought a GAS amp, preamp, tuner and moving coil cartridge, Counterpoint in the 80's and Vandersteen speakers in the 90's. I also brought a few friends in and they all bought equipment from them. One friend in particular has spent just south of 800K on his system at Natural Sound..
About 10 years ago, I bought a demo Marantz 8001 SACD player and needed some high end interconnects for them. To make a long story short, I got royally screwed on the pair of cables and when I brought this to their attention, nothing. I sent the owner who I was friends with an email explaining everything and still nothing. They will never, ever get another cent of my money and I also tell all my friends not to shop there now.
